Busted radiator

So, my radiator popped a pretty bad leak on the top end and is leaking coolant at a pretty good clip. I am going to replace the radiator and there are several different options but I need to understand the differences. The radiators from Oreilly are around $300 they are Murray radiators and have a Copper/Brass core. The ones from Autozone are the same price but have Aluminum cores. Then I found one from JC Whitney that is $120 and has an aluminum core and a plastic "end tank" (what is an end tank).

I would assume that the Copper/Brass unit from Oreilly is probably the way to go but why would the one from Whitney be so much cheaper? What is an "end Tank" and would I be taking a significant risk by getting the $120 unit as opposed to the more expensive ones?

Here are the links to oreilly and whitney:

That JC one looks like it's got plastic end tanks...... I wouldn't even think about that one!



The Murray looks like an OE one.

Yeah, the whitney one has plastic end tank. What is the deal with that? Why should I not use a radiator with plastic end tank? Are they prone to failure?

I had to replace the original rad in my F150, witch was still perfectly fine, but had a hair line crack in the plastic end tank, and would leak once pressure builds...

Ok here us the deal with the radiator delima, copper and brass are way better conductors so they are obviously a better material for a radiator. I replaced mine about a week ago so I have some insight into this topic. The tig welded aluminum ones with aluminum tanks are made in usa and will not rot like the copper and brass ones that have about a 15-20 life span due to the brass getting soft I went with the all aluminum radiator for quality however I have noticed a difference in the cooling, my truck will move the gague a small amount when I pin it going up a long grade that it never did before with the copper radiator. So go cooper if you are going to do a lot of hauling, go aluminum for price and longevity

not saying you are wrong, but your findings are the total opposite of what others have reported with quality allum rads.

Well turbo I wish you were right but my experience has been that the copper has better performance than the aluminum as far as I can tell.
